摘要

在水利工程规划设计工作中,对工程所在流域的径流特征进行分析是非常重要的内容。径流特征分析方法一般以代表站的径流时空变化分析为主,具体有径流组成、年内分配规律、年际分配、年际变化趋势等指标。文章以汤旺河下游右岸支流西南岔河为例,采用数理统计方法对流域径流特征进行了实例分析,概括性得出了流域径流年内、年际间变化差异较大,多年演变趋势整体上呈现减少的初步结论。
        In the planning and design of water conservancy project, it is essential to analyze the runoff characteristics of the basin where the project is located. The main analysis method of runoff characteristics is the spatial and temporal variation of runoff at representative stations, including runoff composition, annual distribution law, inter-annual distribution, inter-annual variation trend and so on. Taking Chehe River on the right bank of the lower reaches of Tangwang River as an example, this paper analyzes the runoff characteristics of the basin using the mathematical statistics method, and draws a conclusion that the annual and inter-annual variation of the runoff in the basin is quite different from each other. On the whole, the trend of evolution over many years shows a preliminary conclusion of decreasing.
